Real Money, Real Lessons: In a course called learning by giving, students pursue and allot funding for area nonprofits

Students learn nonprofit ropes by seeking funding for area organizations.

Giving Thanks

Indulge me for a few moments, will you? I write this column just as we approach the Thanksgiving. You will read it having spent the last few weeks recovering from the Christmas Holidays. It seems appropriate at this time, even conventional, to spend a few moments looking at what we all have to be thankful for, even joyous about. All too often the quotidian cares of life weigh us down unceremoniously, and we forget that we have much to be thankful for.

Giving up reporting the aggressor: reports of female victims of domestic violence

The goal of this study is to describe the experience of female victims of domestic violence, who forfeited the lawsuits against their aggressors. The interviews were oriented by the question: What was your experience of forfeiting the denunciation of your aggressor? Three themes emerged from the convergence of the testimonies: time passed from the aggression to the denunciation and then to the forfeiting; the partner, the family, the women's precinct; reflecting about the experience, which described the studied phenomenon. The women expressed ambiguous feelings for their aggressor: affection, anger, humiliation and fear. They recognize that they are dominated and humiliated, but notions of justice and equality between spouses do not appear in the testimonies. Forfeiting can be understood in the context of the reproduction of the traditional family structure, conditioned to economic and social factors. Results highlight implications about the role of the Women's Precinct and the healthcare institutions in the care for women who were victims of domestic violence.

Conditions giving rise to intense visible room temperature photoluminescence in SrWO4 thin films: the role of disorder

The nature of intense visible photoluminescence at room temperature of SrWO4 (SWO) non-crystalline thin films is discussed in the light of experimental results and theoretical calculations. The SWO thin films were synthesized by the polymeric precursors method. Their structural properties have been obtained by X-ray diffraction data and the corresponding photoluminescence (PL) spectra have been measured. The UV-vis optical spectra measurements suggest the creation of localized states in the disordered structure. The photoluminescence measurements reveal that the PL changes with the degree of disorder in the SWO thin film. To understand the origin of visible PL at room temperature in disordered SWO, we performed quantum-mechanical calculations on crystalline and disordered SWO periodic models. Their electronic structures are analyzed in terms of DOS, hand dispersion and charge densities. We used DFT method with the hybrid non-local B3LYP approximation. The polarization induced by the symmetry break and the existence of localized levels favors the creation of trapped holes and electrons, giving origin to the room temperature photoluminescence phenomenon in the SWO thin films.

Thou Shall Not Kill: Vegetarianism in the Christian Faith

Biblical justifications for a vegetarian diet seem to meet with much adversity within mainstream American culture. Texts suggesting that people were intended to be vegetarians can be found in the Bible. However, this interpretation of Biblical texts has not been widely accepted by Protestant Christianity. This research attempts to identifY social and religious characteristics of people who are vegetarian. Fundamentalism, denomination, belief in the inerrancy of the Bible, and strength of belief in Christianity are examined as factors related to supporting vegetarianism. The General Social Survey's data from 1993 and 1994 were used in this study. The data were analyzed using frequencies, means, cross tabulations. correlations, and regressions. The sample was 57% female and 87% white, the mean age was 46 and the average level of education was 13 years. The study found that, among the independent variables. belief in animal rights, rather than any specific religious views, had the strongest influence on vegetarianism.

Reproductive interference between two sibling species of gift-giving spiders

We investigated the possibility of reproductive interference between two sibling spider species, Paratrechalea azul and Paratrechalea ornata, which occur syntopically and reproduce synchronously. Males of both species offer a nuptial gift composed of prey wrapped in silk to females. Through laboratory experiments, we evaluated possible asymmetries in the outcome of heterospecific encounters between males and females, and investigated whether chemical signalling could function as a premating barrier between the two species. Males of P. azul were unable to discriminate conspecific from heterospecific female draglines, which resulted in wasted time and energy in nuptial gift construction. Males of P. ornata incurred a higher cost for discrimination mistakes because most of them were attacked by heterospecific females; 95% lost the nuptial gift upon the attack and 33% were preyed upon. This pattern is probably a consequence of differences in body size between males and females of each species. Both species showed erroneous female choice, but only P. ornata females courted heterospecific males, which are considerably larger than conspecific males and may resemble high-quality mating partners. Males of P. ornata also made discrimination mistakes, but at a much lower frequency compared to P. azul males. The selective pressure for precise recognition of conspecific female signs is probably stronger on P. ornata males because misdirected courtship may increase their chances of encountering predatory heterospecific females. This study provides the first detailed evidence of reproductive interference between two reproductively isolated spider species, showing that the costs paid by individuals of different sexes and different species are highly asymmetric.

Introducing education for sustainable development in the undergraduate laboratory: quantitative analysis of bioethanol fuel and its blends with gasoline by using solvatochromic dyes

The concept of Education for Sustainable Development, ESD, has been introduced in a period where chemistry education is undergoing a major change, both in emphasis and methods of teaching. Studying an everyday problem, with an important socio-economic impact in the laboratory is a part of this approach. Presently, the students in many countries go to school in vehicles that run, at least partially, on biofuels; it is high time to let them test these fuels. The use of renewable fuels is not new: since 1931 the gasoline sold in Brazil contains 20 to 25 vol-% of bioethanol; this composition is being continually monitored. With ESD in mind, we have employed a constructivist approach in an undergraduate course, where UV-vis spectroscopy has been employed for the determination of the composition of two fuel blends, namely, bioethanol/water, and bioethanol/gasoline. The activities started by giving a three-part quiz. The first and second ones introduced the students to historical and practical aspects of the theme (biofuels). In the third part, we asked them to develop a UV-vis experiment for the determination of the composition of fuel blends. They have tested two approaches: (i) use of a solvatochromic dye, followed by determination of fuel composition from plots of the empirical fuel polarity versus its composition; (ii) use of an ethanol-soluble dye, followed by determination of the blend composition from a Beer's law plot; the former proved to be much more convenient. Their evaluation of the experiment was highly positive, because of the relevance of the problem; the (constructivist) approach employed, and the bright colors that the solvatochromic dye acquire in these fuel blends. Thus ESD can be fruitfully employed in order to motivate the students; make the laboratory "fun", and teach them theory (solvation). The experiments reported here can also be given to undergraduate students whose major is not chemistry (engineering, pharmacy, biology, etc.). They are low-cost and safe to be introduced at high-school level.

A quantitative analysis of current security concerns and solutions for cloud computing

The development of cloud computing services is speeding up the rate in which the organizations outsource their computational services or sell their idle computational resources. Even though migrating to the cloud remains a tempting trend from a financial perspective, there are several other aspects that must be taken into account by companies before they decide to do so. One of the most important aspect refers to security: while some cloud computing security issues are inherited from the solutions adopted to create such services, many new security questions that are particular to these solutions also arise, including those related to how the services are organized and which kind of service/data can be placed in the cloud. Aiming to give a better understanding of this complex scenario, in this article we identify and classify the main security concerns and solutions in cloud computing, and propose a taxonomy of security in cloud computing, giving an overview of the current status of security in this emerging technology.
